Hello, Our IT team has updated our Koha from 18.05 to 20.05 and we are getting login errors for some of the superuser librarians on our team. Some are able to log in while others, including myself, are not. I can access the login page to type in my credentials, but after I submit it, I receive the following error. Software error: {UNKNOWN}: Configuration not defined at /usr/share/perl5/Log/Log4perl/Config.pm line 579. at /usr/share/koha/lib/Koha/Patron.pm line 345 For help, please send mail to the webmaster ([no address given]), giving this error message and the time and date of the error. Has anyone experienced this? If so, what did you do to resolve it? -- *Monica Benavides* *Library Assistant/Testing Center Coordinator* –––––––––––––––––––––––––––––––––––––––––––––––––––– *Rocky Mountain University of Health Professions* 122 East 1700 South, Building 3, Provo, Utah 84606 Direct: 385.375.8772 *|* Campus: 801.375.5125 –––––––––––––––––––––––––––––––––––––––––––––––––––– *Stay connected, learn more!* Blog <https://rmuohp.edu/about-the-university/university-news/> | Facebook <https://www.facebook.com/RMUoHP> | Twitter <https://twitter.com/rmuohp> | YouTube <https://www.youtube.com/user/TheRMUoHP> | rm.edu
